The 15-year-old boy was arrested after he ran to fields three miles away,
during which time he got rid of most of his outer clothing.

Detectives from the Metropolitan Police’s Flying Squad linked the robbery to
another at a jewellers in Mayfair on June 7, by Alura and a 16-year-old boy.

The pair entered the shop on the pretext of discussing custom jewellery, but
instead jumped over the counter and threatened staff, pretending they had a
gun.

This time Alura wore false waist-length dreadlocks.

Police found fingerprints belonging to them both on paperwork – including
school homework and a drawing of the plan of the store – which was left at
the scene.

Detective Constable Vicky Bailey, of the Flying Squad, said: “These were
violent armed robberies during which innocent members of staff were
terrorised and genuinely feared for their lives.

“It is even more shocking to know that this level of violence was
inflicted by three schoolboys who went to extraordinary lengths to research,
plan and get away with these offences, demonstrated by Alura’s sophisticated
disguise.

“These young men now face considerable terms of imprisonment where they
will have plenty of time to think about the consequences of their actions.”
